Recently, our family took a trip to London & Paris. I was so nervous about booking a hotel until I found the Tripadvisor site. The 2 hotels I ended up booking were exactly what I expected. People write in with their experiences there and even post their own photos from places all over the world. If not for this site, I would have booked a hotel in London that was known to have bedbugs. Not only can you get hotle advise but you can get advise for restaurants, itineraries, and other vacation planning tips. I felt like I knew Paris before going from all the tips on each neighborhood etc.
